The guys over at www.sonicanime.net have been kind enough to provide us with all sorts of info on the new Sonic X series, including beginning to subtitle and post episodes! Over at www.sonicanime.net/episodes.html you can find the first episode for download with english subtitles, the second episodes for download, apparently raw, and a preview of the third episode, along with other goodies!
Enjoy!
P.S. Can we not turn this into a sordid debate about how legal this is or is not? This sort of fansubbing is freely distributed, not for profit, and not taking money away from the people who make this anime, since no DVD of this anime is yet available, even in Japan, so it's all okay. 'nuff said.
